Lying alongside mountains of smelly garbage under the South American sun, Cateura is a long way from the conservatories of Prague or Vienna. Yet the township, which grew out of Paraguay's largest dump(垃圾场), is gaining a reputation as a hothouse for musical talent and for its youth orchestra(管弦乐队) that plays instruments made from garbage. "The world sends us garbage. We send back music," says Favio Chavez, leader of the "Recycled Orchestra," during a recent visit by the group to Los Angeles. Orchestra members, poor children from Cateura, play violins fashioned from oven trays and guitars made from dessert dishes. The orchestra provides the youngsters an outlet and an escape, a chance to go beyond the mess of their slum(贫民窟) through the music of Mozart, and even Sinatra. "In the beginning, it was difficult to play," says the l0-year-old violinist Celeste Fleitas." But Favio helped me learn over time. From Favio, I have learned to be more responsible and value the things I have."

    The destination for more than 1,500 tons of waste each day, the community has no safe drinking water and little access to electricity or sanitation(卫生设施). Illiteracy is severe, and the children of the township often fall into drugs, violence and crimes.

    Favio Chavez, a musical talent, came to Cateura as an environmental technician in 2006 and started a youth music school. He knew shop-bought instruments were beyond the means of villagers whose sheds are worth less than a violin, so he approached a carpenter to make some out of waste from the dump.

    The orchestra caught the eye of Paraguayan filmmaker Alejandra Amarilla. She uploaded a short piece of the orchestra to YouTube in 2012, hoping to secure crowdfunding for what would become Landfill Harmonic, a documentary released across the United States this month and promoting the youngsters on a tour of the world's music halls later on.
